Contribution à l'étude de l'armoise blanche (Artemisia herba alba L.)

Terpenes from Artemisia herba-alba.

Chromatographic investigation of the methylene chloride/methanol extract of the aerial parts of Artemisia herba-alba afforded a new monoterpene dimer, in addition to a known monoterpene and three known sesquiterpene lactones. The structures of the compounds were determined by comprehensive NMR analyses, including DEPT, COSY, HMQC, HMBC, and HRMS.

Essential oil composition of Artemisia herba-alba from southern Tunisia.

The composition of the essential oil hydrodistilled from the aerial parts of 18 individual Artemisia herba-alba Asso. plants collected in southern Tunisia was determined by GC and GCMS analysis. The oil yield varied between 0.68% v/w and 1.93% v/w. One hundred components were identified, 21 of of which are reported for the first time in Artemisia herba-alba oil. The oil contained 10 components ...

Antibacterial and Antioxidant Activities of Essential Oils from Artemisia herba-alba Asso., Pelargonium capitatum × radens and Laurus nobilis L.

Essential oils are natural antimicrobials that have the potential to provide a safer alternative to synthetic antimicrobials currently used in the food industry. Therefore, the aim of this study was to evaluate the antimicrobial and antioxidant activities of essential oils from white wormwood, rose-scented geranium and bay laurel against Salmonella typhimurium and Escherichia coli O157:H7 on fr...

بررسی کمی و کیفی عصاره متانولی گیاه artemisia herba alba

گیاه آرتمیزیا هربا آلبا (a.herba.alba) از ارتفاعات تفتان واقع در استان سیستان و بلوچستان در مرداد سال 1389 جمع آوری شد. عصاره گیری گیاه با حلال متانول توسط دستگاه سوکسله انجام و سپس عصاره به وسیله دستگاه تقطیر در خلاء تغلیظ شد. مطالعه گسترده بر روی عصاره متانولی نمونه های مختلفی از این گونه انجام گردید. برای استخراج آلکالوئیدها، با اسید سولفوریک عصاره را اسیدی و برای حذف مواد ترپنوئیدی و چربی ه...
